So am I to assume that if I do not have Traction Contol, I will only have 1 TPS? Also as Lexus 92 was having with his actually having trouble with his overdrive, can someone describe in detail the problem a bad TPS will cause. I would like to compare with my problem of hesitation when cruising at 1800 RPM. If I let off just a little and reapply the gas - it feels like a miss. I can make it happen at will. I have changed the plugs - but not the wires yet.
I plan to check the wires first chance I get. But my gut says that is not the problem.... Thoughts?

Also can the TPS be ordered from a Toyota dealer or Lexus only?

Thanks All! 92 LS 400 115,000m

Hi FaceUT ,

I am wondering did you solve the hesitation when cruising at 1800RPM??? Please update. I think I have same problem on my 94 LS400 Intermitent when acceletate. Please let me know. BTW did you change your TPS???

Thanks.

Yep, for me the TPS was the fix. Totally eliminated the 200-300 drop in RPM's when letting off slightly at 1800. Run a search on this thread for much more info.

Hi there,

I own a 1991 LS400, i have a traction control problem en it points to the TPS.
I want to measure it but i cant find the specs in the book.
On the net i found i manual @ .ru but is said between 0,8-1.0 ohm.
I measure 1,3 ohm at the trac sub TPS actuator and when i measure the TPS itself with a 40 mm gauge it said more then 0,5 ohm.

What to do ?
